Kinda new hi guys, Anyone know anything about this pedal? :scratch:

Hi guys,

The recording studio I am based at has some NOS valves for sale on ebay. It includes some ECC82s and EF86. It might be worth your while taking a look. You can see them at

Cheers,

I just bought the ModTone PB8 powered pedal board and their power specs don't seem to make much sense. Now, it wasn't my first choice, but I scored one pretty cheap on the bay, so I decided to give it a shot. The wall-wart they included is rated for 450mA at 9v... Fine, no surprises there. The weird thing is that they've given each individual outlet a 100mA maximum current rating. Not sure where that comes from. The outlets are just mounted on a PCB, no extra components besides a resistor and a...

Anyone got something to swap for an original Hot Cake? I'm after something different but in a similar vein...OCD, Plexi-drive...crunchy, amp-like distortion. The Hot Cake isn't quite suited to my needs at this time.

P/X considered. I'm in the UK but would consider overseas exchanges too for the right thing.

Hey guys,

found pic of guts of this custom shop Providence PFX-3B Vandal Bass Distortion. Will post better pics when I'll receive it.

As it's opened waiting for some components to finish the cap job, i thought i might as well post some gut pics here in case it helps someone.

Polytone minibrute I from 86 apparently.
the layout and components seem to match exactly the schematics found on murchmusic website, except that the preamp only has the most basic features : no reverb or distortion.

Enjoy

EDIT: In these pics: some parts are missing as i am waiting for them to be delivered.
Power amp misses : 2 4000uF caps, 1 1uF non...

Hello guys, I posted this on the amp forum, but theres no answer so i thought maybe here someone would have an idea..

I would like to add a reverb to a polytone amp (without reverb) i grabbed used a few weeks ago. As advised, i'm changing all electrolytic caps into it at the moment and i thought that as it's opened, it would be a great time to add reverb to it.
However, i am not sure how i could do that: mainly, where should i take the signal into the preamp path, and where should i reinject...

I am looking around to find a large enclosure for rehousing a Boss ce-1. I would need to be 5 deep and 7 wide at least, and about 11/2 high. I checked Hammond and could not find anything wide and deep enough.

I am in USA.

Thanks in advance.

So I am new to pedal building and as my second project I decided to build a DOD FX25 from
I got everything together and no sound. I ran an audio probe along it following the input and lose signal on the far side of R23. It sounds like the circuit is complete (ie no noise) but no guitar sound either. I swapped out the resistor and still no sound. Is it possible it is not the resistor but something else on that side of the circuit? IC2 maybe?

Not sure if a link to this website has been posted in this thread already, but anyway, just thought some of you might be interested in this:

I've noticed that my amp has become much quieter recently. It's generally a really loud amp and I've rarely needed to push it past '2' at rehearsals, even with a heavy handed drummer, but I've had to gradually turn it up more over the past few weeks even though I'm in a pretty quiet band and a fairly dead room. It might not sound like much but I was on 4-5 at last rehearsal, which would be uncomfortably loud before.

The only thing which has changed recently is that we have our own rehearsal...

Well, Hurricane Sandy has given me a few days off with little to do so I have put together the project files for the ButterCup.
The ButterCup uses high gain Germanium transistors. I bought them from Pedal Parts Plus in the US. The enclosure is a 1590XX as this pedal requires two 3PDT switches and 4 Pots. This is not a project for a beginner!!!!

I am currently using AC187 germaniums for Q1 and Q2 and a 2N5088 for Q3. Using the silicone 2N5088 removes some noise from the pedal, and adds a...

There was no Build Your Own Community Pedal category, so if this should be in another sub-forum then by all means relocate it!

Here is the schematic for the Octophant, a pedal we threw together over at Harmony-Central's FX forum. It is similar to a fuzzrite but with 2n7000's. The octave up is from the push-me-pull-you. The boost circuit is a simple gain stage with an AC187. It isn't the most groundbreaking thing in the world, but it sounds cool and we had a ton of fun tweaking the design....

I accidentally posted the build report in the workbench section, so here's the link:

Hey guys,

I'm looking for a little help in finding the right components for the following fuzz face circuit:

I've been looking on Small Bear, but I don't think they have the right capacitors I'm looking for. I'm wanted to check to see as well if the following trimpot will be big enough to fit in the required space:

I was planning on using BC108 transistors and was wondering if anyone has used the Small Bear BC10x work-alike transistors. I've got plenty of resistors already but I was...

Hey guys, tonight I worked on my 3rd 1484, I replaced the power caps, added a 3 prong plug, electrolytic caps in the pre amp, and added a new mojotone output transformer and it has nothing but hum when I switch it on.

I've done 2 other 1484, one changing just the caps and adding a 3 prong plug, and the other I did the same thing as above but it worked just fine. I will post pictures tomorrow because i've been hard at it on this amp for hours and it not working is pretty much making me need...

Hi all. Hope I'm posting this in the right place. I'm wondering if anyone has tried building a hybrid of an Octavia with the octave section of the circuit taken from a FTM. I've been looking for a good versatile octave fuzz. I have a Devi Ever Godzilla that's going up on Ebay soon because it's just TOO crazy. Didn't like the sound of the Joyo Ultimate Octave (even after the mod presented on this forum), and from what I understand the Joyo is based on the GGG FTM as well. What I like about demos...

hello!!

Please excuse my english!, i'm writing from chile!

i'm starting this topic since it wasn't created yet!...searching at google found this pics!

I would like to know how the add ons of this pedal are made... as everybody knows its a refined tubescreamer with active tonestack... but in the simple version there is only bass and treble so here is the first question...

how we can add to the simple bb schematic a mid control?, it necessary must be an active circuit?

A second switch works...

Hi There,

I'm lucky enough to have an MN3005 and would really like to build an AquaPuss to MK1 specs.

Anyone have one to sell me?

Alternatively, I would also be open to having someone build me the pedal, minus the ICs. I like to focus more on playing rather than drilling holes in enclosures in my yard!

Kind regards,

John

Hey Just saw this. This is a pretty ambitious Kick-starter program but figured it should be viewed here so I post it.. I have no involvement with it..

can someone help me ? i live in brasil, and right here a original electro harmonix pulsar costs like 250 dollars, so i decided to make my own. i already did the andervol circuit to my volume pedal, and the bluesbreaker, but yesterday i decided to start de pulsar, and i read about the rate pot fix, and some other mods. so i did the fix on the pcb layout, and i put a 10k lin pot. the fx worked, but i think the rate is too fast, how can i lower the velocity of rate ? change the value of r14 works...

There is thread about older unit, but I want to make one with unit that has LED,and different circuit.....
fuzz is different, and wah section is standard ,but have FET input buffer and 100K instead 10K emiter to ground resistor R107 on pictures...

more to come.....
